Kenwood KDC-138 Operation Problem

I bought a used jeep with a Kenwood model KDC-138 cd player already installed. I did install an amplifier and subs on my own. This did not prove to be a problem as I have done so many times before. The system worked well for about a month. After fueling my vehicle one evening I found that when I started the jeep the stereo was not working. The only thing the unit will display is "dcer" and nothing functions. What could the problem be?

Here's the quote from the manual regarding "dcer": "The speaker wire has a short-circuit or touches the chassis of the vehicle and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT/DCER" code does not disappear, consult your nearest service center "

I believe the manual can be downloaded from crutchfield .com after you go to the Kenwood KDC-138 page on their website. The reset button is either on the lower left of the face or, removing the face, on the lower left of the body. Hope this helps you.

I bought a used car and it already had a kenwood kdc-x890 installed. my question is when i plug my zune or even just a mp3 player into the usb port it responds with [n/a data].


The KDC-X890 will play MP3s that are stored on a USB mass storage device, such as a USB thumb drive. It won't play music from another MP3 player such as a Zune through the USB port, but you could plug your MP3 player into the auxiliary jack.

Kenwood kdc-138, NO SOUND, CD PLAYER NO RESPONDING


First thing you need to do is make sure you dont have a short in the speaker wires.. if any one of them touches ground it kills the system.. then you have to remove all the wires and start over... disconnect the battery... remove all the speaker wires only and then turn it on and reset it... then again remove the battery from the car and install them all make sure nothing is touching then turn it back on and see if that works.. you can also test to make sure you speaker wires are good by using a 9v battery and touching positive and negative of each speaker to the positive and neg of the battery... JUST FOR A SECOND it will pop.. that means your wires are good and no shorted to that speaker.
